Step-by-step explanation:

Volume of a Cone

The volume of a right circular cone with height h and a base radius r is:

[tex]\displaystyle V=\frac{1}{3}\pi r^2 h[/tex]

The height of the given cone is h=4.1 cm and its diameter is d=14.8 cm. Since the radius is half the diameter, r=7.4 cm.

Calculate the volume:

[tex]\displaystyle V=\frac{1}{3}\pi\cdot 7.4^2\cdot 4.1[/tex]

[tex]\displaystyle V=\frac{1}{3}\pi\cdot 54.76\cdot 4.1[/tex]

[tex]\displaystyle V=\frac{1}{3}\pi\cdot 224.516[/tex]

[tex]\boxed{V=235.1\ cm^3}[/tex]

Answer:

Step-by-step explanation:

By definition, the power of each term in a polynomial must be greater than or equal to 0.

So x/5+2 is a polynomial

4x+sqrt(x)-1 is not because sqrt(x) is x^(1/2)

35x^2 is a polynomial

7x^7-x^(-5) is not because -5 is less than 0.

Thickness of a 500 sheet stack of notebook paper is 5 cm.

What is Measurement units?

A measurement unit is a standard quality used to express a physical quantity.

Given that;

Thickness of a sheet of notebook paper = 0.004 inch

Now,

1 inch = 2.54 cm

Hence, Thickness of a sheet of notebook paper = 0.004 inch

                                                                          = 0.004 × 2.54 cm

                                                                          = 0.01016 cm

                                                                          = 0.01 cm

So, Thickness of a 500 sheet stack of notebook paper = 500 × 0.01

                                                                                    = 5 cm

Thus, Thickness of a 500-sheet stack of notebook paper is 5 cm.

Answer:

There is no sufficient evidence to conclude that population mean number of times that adults go out for dinner each week is less than 1.5

Step-by-step explanation:

From the question we are told that

   The  population mean is  less than  1.5

   The sample size is  n  =  7

   The sample data is   2, 0, 1, 5, 0, 2, and 3

Generally the sample mean is mathematically represented as  

     [tex]\=  x =  \frac{ \sum x_i }{ n }[/tex]

=>  [tex]\=  x =  \frac{ 2 +  0 +  1 +  5 +  0 +  2 +   3 }{ 7 }[/tex]

=>  [tex]\=  x =  1.857 [/tex]

Generally the standard deviation is mathematically represented as

      [tex]\sigma  =  \sqrt{\frac{\sum (x_i - \= x)^2}{n} }[/tex]

=>   [tex]\sigma  =  \sqrt{\frac{ (2 -   1.857)^2 +  (0 -   1.857)^2 +\cdots  (3 -   1.857)^2}{7} }[/tex]

=>   [tex]\sigma  =  1.773[/tex]

The null hypothesis is  [tex]H_o :  \mu  =  1.5[/tex]

The alternative hypothesis is [tex]H_a  :  \mu  < 1.5[/tex]

Generally the test statistics is mathematically represented as

     [tex]z  =  \frac{\= x  -  \mu }{ \frac{\sigma }{\sqrt{n} } }[/tex]

=>   [tex]z  =  \frac{\= x  - 1.857 }{ \frac{1.773 }{\sqrt{7} } }[/tex]  

=>[tex]z =  0.53[/tex]

Generally the p-value is mathematically represented as

      [tex]p-value  =  P(z  < 0.53 )[/tex]

From the z-table  

        [tex]P(z  <  0.53 ) =  0.70194[/tex]

So

       [tex]p-value  =  0.70194[/tex]

From the values obtained we see that [tex]p-value  >  0.05[/tex]  

Here there is no sufficient evidence to conclude that population mean number of times that adults go out for dinner each week is less than 1.5

The check register is used to show the total amount Taquan spent

Using the assumed values, Taquan's initial balance is $1336.26

The question is incomplete, as the check register is not shown.

So, I will give a general explanation

Assume that the utility bill is $241.46

From the question, the new balance on March 24 is $1094.80

This means that the initial balance is:

Initial balance = New balance + Utility bill

This gives

Initial balance = $1094.80 + $241.46

Evaluate the sum

Initial balance = $1336.26

Using the assumed values, Taquan's initial balance is $1336.26

There are 24 different ways 4 students can be arranged in a row.

A permutation in math is the number of ways in which a set of data or objects can be ordered or arranged, where the order matters.

Given that, a family of 4 brothers are to be seated in a row at a theatre,

We need to determine the order of the possible seating arrangements,

we conclude that there are =

Answer:

A) The expression that shows the regular price minus the discount is r - 6

B) The function is p(r) = 1.05r - 6.3

C) You would pay $14.7 during Bargain Days

Step-by-step explanation:

∵ The regular price is r

∵ The discount on it is 6%

∴ The price after the discount = r - 6

A) The expression that shows the regular price minus the discount is

     r - 6

∵ The state sales tax is 5% applied after the discount

∴ The sales tax = 5%(r - 6)

→ Change 5% to decimal y dividing it by 100

∵ 5% = [tex]\frac{5}{100}[/tex] = 0.05

∴ The sales tax = 0.05(r - 6) = 0.05(r) - 0.05(6)

∴ The sales tax = 0.05r - 0.3

∵ p is the price of the T-shirt with discount and sales tax

→ Add the sales tax to the regular price minus the discount

∴ p(r) = r - 6 + 0.05r - 0.3

→ Add the like terms

∴ p(r) = (r + 0.05r) + (-6 - 0.3)

∴ p(r) = 1.05r + (-6.3)

∴ p(r) = 1.05r - 6.3

B) The function is p(r) = 1.05r - 6.3

∵ The regular price of a shirt is $20

→ Substitute r by 20 in the function above to find how much you would

   pay during the Bargain Days

∴ p(20) = 1.05(20) - 6.3

∴ p(20) = 21 - 6.3

∴ p(20) = $14.7

C) You would pay $14.7 during Bargain Days
